Hi tech32, This issue may occur if the full format process cannot complete correctly. For example, this issue may occur if the cluster size that is specified for the full format is too large to format the disk. Try formatting the Flash Drive and check.For more information, see:How to use Disk Management to configure basic disks in Windows XP Also this could issue could occur if there are issues with partitioning. Delete and re-create the partition on the Flash drive from the DiskManagement. Refer the link above to do the same.
